This is my simple implementation of the ARRL Antenna Book design equations for the axial-mode helical antenna.

Simple implementation of the ARRL Antenna Book design equations for the axial-mode helical antenna.

The page discusses Axial-Mode Helical Antennas, focusing on turning helical antennas over perfect ground and modeling helices in NEC-2 for optimized design. It covers topics such as high-gain performance, broadband, impedance matching, radiation pattern, feedline, balun, near field, far field, and DIY applications.
